.dart

import 'dart:html'; import 'package:paper_elements/paper_input.dart'; import 'package:polymer/polymer.dart';  /// polymer `<main-app>` element. @customtag('main-app') class mainapp extends polymerelement {   @observable string reversed = '';    /// constructor used create instance of mainapp.   mainapp.created() : super.created();    void reversetext(event event, object object, paperinput target) {     reversed = target.value.split('').reversed.join('');     print(reversed); // nothing shown in console   } 

.html

<!-- import polymer-element's definition --> <link rel="import" href="../../packages/polymer/polymer.html">  <link rel="import" href="../../packages/paper_elements/paper_input.html">  <polymer-element name="main-app">   <template>     <style>       :host {         display: block;       }     </style>      <paper-input label="type something..." on-keyup="{{reversetext}}"></paper-input>      <p>       reversed: {{ reversed }}     </p>   </template>   <script type="application/dart" src="main_app.dart"></script> </polymer-element> 

the print statement in main_app.dart not print visible console.

ensure have intellij debug plugin installed in dartium.
